肺炎支原体抗体滴度与肺炎支原体肺部感染成年患者CT影像特点的相关性分析

目的探讨肺炎支原体肺部感染成年患者CT影像特点与肺炎支原体抗体滴度的相关性。方法选取2017年4月-2018年10月于河南省中医院门诊或住院治疗的72例肺炎支原体肺部感染患者作为研究对象,对患者CT影像学特点和肺炎支原体抗体滴度水平资料进行整理,并对两种检查结果的相关性进行统计分析。结果72例患者中早期MP抗体滴度以1∶80为主,占比29.17%,其次为1∶40和1∶160,均占比15.28%。72例患者中单肺病变58例,其中以右肺上叶和左肺下叶较多分别有22例和18例,占比30.56%、25.00%。CT表现以磨玻璃影、实变影和结节影为主,分别有61例、50例和32例,占比84.72%、69.44%和44.44%。肺炎支原体肺部感染患者MP抗体滴度为1∶40、1∶80、1∶160时以磨玻璃影为主要表现,1∶320、1∶640表现为磨玻璃影和结节影共存,1∶2560、1∶5120表现为磨玻璃影、结节影和实变影同存,1∶10240则以实变影为主要表现。经相关性分析结果显示,MP抗体滴度等级与实变影发现率有相关关系(r=0.746,P=0.021)。结论成人肺炎支原体肺炎患者在CT表现上具有一定的特征,早期肺炎抗体滴度与肺实变呈正相关,与其他肺部CT表现无明显相关性。

Correlation between Mycoplasma pneumoniae antibody titer and CT imaging features of adult patients with Mycoplasma pneumoniae pulmonary infection

OBJECTIVE To explore the correlation between the CT imaging features of the adult patients with Mycoplasma pneumoniae pulmonary infection and the Mycoplasma pneumoniae antibody titer.METHODS A total of 72 patients with M.pneumoniae pulmonary infection who were treated in outpatient department or hospitalized in Henan Hospital of Traditional Chinese Medicine from Apr 2017 to Oct 2018 were recruited as the study objects,the data of the patients including the CT imaging characteristics and Mycoplasma pneumoniae antibody titer were collated,and the correlation between the results of two examination was statistically analyzed.RESULTS Among the 72 patients,the early MP antibody titer was mainly 1∶80,accounting for 29.17%,followed by 1∶40 and 1∶160,both accounting for 15.28%.Among the 72 patients,58 cases had mono-pulmonary lesions,among whom 22 were found in the upper lobe of the right lung,18 cases in the lower lobe of the left lung,accounting for 30.56%and 25.00%respectively.As for the CT manifestations,there were 61(84.72%)cases of ground glass shadow,50(69.44%)cases of consolidation shadow and 32(44.44%)cases of nodular shadow.The ground glass shadow was the major manifestation of the patients with M.pneumoniae pulmonary infection when the MP antibody titers were 1∶40,1∶80 and 1∶160;ground glass shadow and nodular shadow coexisted when the titers were 1∶320 and 1∶640;ground glass shadow,nodular shadow and consolidation shadow existed at the same when the titers were 1∶2560 and 1∶5120;the consolidation shadow was the major manifestation when the titer was 1∶10240.The result of correlation analysis showed that the level of MP antibody titer was associated with the discovery rate of consolidation shadow(r=0.746,P=0.021).CONCLUSION The adult patients with M.pneumoniae pulmonary infection show certain characteristics in CT manifestations.The early pneumonia antibody titer is positively correlated with the lung consolidation but is not remarkably associated with other lung CT manifestations.
